TISKILWA — An excavation hazard notice has been sent to property owners of a three-acre area surrounding the 2011 train derailment site just east of Tiskilwa.

According to that notice sent out by the Illinois Environmental Protection Agency (IEPA), the impacted groundwater is generally located 13 to 15 feet below the ground surface. No residences or commercial buildings are located in this area. The area of impacted shallow groundwater includes agriculture fields and railroad right-of-way.

The Iowa Interstate Railroad (IAIS) is working with the IEPA to develop appropriate signage for the area, according to Michelle Tebrugge, IEPA community relations coordinator.
